luis: What are your impressions of those other three; 200, 300, & 400? Getting at Attila's comments, I'm wondering what to expect.

400- wonderful ! very sharp wide open, little fringing.

300- lousy. I actually have two of them, one much worse than the other. Very light lens for a 300/5, but if it doesn't deliver...

200 - average for a 200/3.5

I haven't tried any of the 500's, but I have seen good comments on it.

I am curious how much that set you back -if you care to indulge.

$102 with shipping. Given its rarity, I expected it to go much higher. We'll see about the quality after I receive it in another week. I'll be sure to report out here. If you're thinking about my comment about it costing as much as my most expensive lenses, well yes, I'm a tightwad Very Happy But I've landed some very good lenses, all $100 or less.

Congrats on the deal-I think you're a very smart shopper Very Happy -not a tight wad. Jim's camera in Seattle had one(he may still have it)- it was priced quite a bit above what you paid.

Well, the monster arrived today - just three days - not bad. I have yet to do anything with it and now the lighting is too dim. Tomorrow I will see if I can get a few pictures off by holding it up to the camera. It will take me awhile to get the mount situation straightened out.

Today's attempt to use the lens - held to the camera - was a miserable failure. I had a very difficult time focusing and couldn't hold it still enough to get a decent picture. I hope to do better when the mount is converted. If today's pictures were any indication, they are much worse than Attila suggested.

Point of clarification; I actually held the camera to the lens.

I'll put some images of the lens in this thread (I stumbled over the rear part not knowing what it was so did some research). There are two versions of this. One attaches both parts with a screw mount, the other with a bayonet mount. Also it is possible to attach a filter to the rear of the front part (haven't yet found documentation but I found a pic with filter attached)

Just to add a extra curve-ball, the mount register of Komura's reflex housing for screw-mount Leica cameras has a longer register than the Leica Visoflex (PLOOT). Like about 5mm longer. Allows a longer mirror.
